Filed: 1975-02-05
Abstract: 1486673 Infrared gas analyzers HARTMANN & BRAUN AG 5 Feb 1975 [5 Feb 1974] 4914/75 Heading G1A In a double beam infrared gas analyzer which determines the amount of a particular gas in a mixture, one of the beam paths contains a gaseous filter cell filled only with the same particular gas at sub-atmospheric pressure. The mixture to be analyzed flows through cells 6, 7 and infrared from sources 1, 2 passes through it to detector 8. Also in the beam paths are cells 4, 5, one of which is the above mentioned filter cell. The detector is also filled with the particular gas to be measured, and has a capacitor diaphragm 11 which vibrates as chopper 3 modulates the infrared. The gas concentration is measured by applying a conatant voltage to the diaphragm from source 13, and the charging current generates a signal across a resistor which is amplified, rectified and displayed at 14. The use of the filter cell containing only the one gas increases the sensitivity over prior apparatus in which the filter cell also had a buffer gas.
